Today I want to show you a new small feature in ORM Designer 1.4.2 which helps you with navigation in the model. Until now, ORM Designer has shown only three different icons in a column for primary keys, foreign keys and other columns. Today we have added another three types for differentiation of NULL and NOT NULL columns. Empty diamonds beside the column names symbolize columns where NULL is allowed, filled diamonds where value is requried.

Here is screenshot of this feature:

Currently is this feature in beta-version of ORM Designer. Download here: http://www.orm-designer.com/article/orm-designer-beta-versions
